Abstract

This chapter will discuss in detail the nature of one Semantically Enabled Service-oriented Architecture (SESA) compliant system, IRS-III, which also informs the OASIS standardization work on semantic Service-Oriented Architecture. It will also consider tools that have been independently produced to fulfill separate tasks within the architecture, specifically those which address discovery and composition. Next tools from the OWL-S community will be considered from the point of view of the SESA. Finally the METEOR-S toolset, and its input into the WSDL-S standardization will be considered.
